Dynamically detecting and correcting the deactivation of beamforming

ABSTRACT

Methods and systems are provided for dynamically detecting and correcting the deactivation of beamforming from an antenna. One or more users are identified as present within a particular geographic area typically served by beamforming, and the average signal strength of the one or more user devices is monitored. If a threshold level of degradation of the average signal strength is detected, then a beamforming status is determined for one or more of the antennas serving the user device or devices. Based on the determination, corrective measures are taken and beamforming is reactivated.

SUMMARY

The present disclosure is directed, in part, to dynamically detecting and correcting the deactivation of beamforming from an antenna or antennas, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the claims.

In aspects set forth herein, a determination is made that beamforming from an antenna, or antennas, has been disabled or deactivated, and then corrective measures are taken to ensure that beamforming is reactivated. When beamforming becomes disabled or deactivated, users throughout a cell typically served by beamforming could have different levels of degradation of signal strength. This would equate to an overall negative effect to those users' quality of service. While, typically, beamforming failures have to be detected and fixed manually per antenna, here detection and correction of beamforming failures occurs dynamically, decreasing overall time and effort to restore signal strength and quality of service to the users being served in the area.

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used in isolation as an aid in determining the scope of the claimed subject matter.

DETAILED DESCRIPTION

The subject matter of embodiments of the invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” may be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.

In certain aspects, methods are provided for dynamically detecting and correcting the deactivation of beamforming caused by one of various factors. For instance, if the average signal strength for one or more user devices located in a geographical area, traditionally served by beamforming, degrades beyond a threshold amount this could indicate that beamforming has been disabled. When this is the case, a beamforming status message can be requested to confirm the status of beamforming from one or more antennas. If beamforming is disabled, then corrective measures can be taken to reactivate beamforming.

Providing methods and systems for dynamically detecting and correcting the deactivation of beamforming has a wide array of beneficiaries, including the end user using the device in the area of beamforming and the service provider providing service to the device. The end user using the device would be provided clear technical benefits, for example better signal strength relating to overall better performance of their device. This is especially true for users using their device at the edge of the radiation from an antenna, also known as the cell edge. The service provider also is provided clear technical benefits. The service provider is not only able to provide a higher quality service to the end user, but is also able to identify and troubleshoot the deactivation of beamforming dynamically and quickly instead of attempting to identify and correct each beamforming deactivation manually.

In a first aspect, a method is provided for dynamically detecting and correcting the deactivation of beamforming from at least one antenna. The method comprises identifying one or more user devices present in a particular geographic area and monitoring an average signal strength measurement for user device, or devices. The method further comprises detecting a threshold level of degradation of the average signal strength for the user device or user devices and then determining, from an element management system, that the beamforming status of an antenna is disabled. Additionally, the method comprises, based on determining beamforming is disabled, reactivating beamforming.

In another aspect, a method is provided for dynamically detecting and correcting the deactivation of beamforming from at least one antenna. The method comprises detecting, based on an average signal strength measurement of one or more user devices, a threshold level of degradation in the signal strength measurement. The method further comprises triggering a beamforming status detection request by a radio, communicatively coupled to the antenna and an element management system, to the element management system. Further, the method comprises receiving, from the element management system, an indication that beamforming is deactivated and based on indication, determining a failure reason for the beamforming deactivation. Additionally, the method comprises reactivating the beamforming from the antenna or antennas.

In yet another aspect, a dynamic beamforming failure detection system is provided for dynamically detecting and correcting the failure of beamforming from at least one antenna. The dynamic beamforming failure detection system comprises a processor and one or more computer storage hardware devices storing computer-usable instructions that, when used by the processor, cause the processor to identify one or more user devices present in a particular geographic area, and determine that an average signal strength measurement of the one or more user devices has degraded by a threshold amount. The processor further communicates a beamforming status detection request. The processor additionally receives an indication that beamforming from the at least one antenna has been deactivated and then determines a failure reason for the deactivation of the beamforming. If the deactivation was caused by a failure of an antenna line device, the processor then resets the antenna line device and reactivates beamforming. Additionally, if the deactivation was caused by a beamforming calibration failure, the processor reactivates beamforming.

Throughout the description of embodiments of the present invention, several acronyms and shorthand notations are used to aid the understanding of certain concepts pertaining to the associated methods, systems, and computer-readable media. These acronyms and shorthand notations are solely intended for the purpose of providing an easy methodology of communicating the ideas expressed herein and are in no way meant to limit the scope of the present invention.

Further, various technical terms are used throughout this description. An illustrative resource that fleshes out various aspects of these terms can be found in Newton's Telecom Dictionary, 25th Edition (2009).

FIG. 1 provides a diagram 100 which depicts a beam 102 emitting from an antenna 103 encompassing one or more user devices 108 a and 108 b in a particular geographical area in accordance with implementations of the present disclosure. In FIG. 1, a cell site 106 may include one or more antennas 104, base transmitter stations, radios, transmitter/receivers, digital signal processors, control electronics, GPS equipment, power cabinets or power supply, base stations, etc. In embodiments, the one or more antennas 104 are capable of using beamforming as at least one signal processing technique.

As shown, a beam 102 is emitted from the antenna or antennas 104 encompassing user devices 108 a and 108 b. In some embodiments, a user device or devices shown as 108 a or 108 b, may take the form of a wireless or mobile device capable of communication by utilizing a wireless telecommunication network(s). In this example, the user device can be any mobile computing device that communicates by way of a wireless network, for example, a 3G, CDMA, 4G, LTE, WiMAX, 5G or any other type of network.

Further, the cell site 106 may be communicatively coupled to a network 112, providing a possible communication link between the user device(s) 108 a and 108 b and the network 112. The network 112 may be a telecommunications network(s), or portion thereof. A telecommunications network might include one or more devices and components, such as base stations, servers, switches, relays, databases, nodes etc., which are not shown so as to not confuse other aspects of the present disclosure. Those devices and components can provide connectivity in a variety of implementations to form a network 112. In addition the network 112 can be utilized in a variety of manners, such as a single network, multiple networks, or as a network of networks, but, ultimately, is shown as simplified as possible to avoid the risk of confusing other aspects of the present disclosure.

As stated above, network 112 can be part of a telecommunication network that connects subscribers to their service provider(s). In embodiments network 112 could be associated with a specific telecommunication provider that provides services (e.g. LTE, voice, location, etc.) to user devices, such as user device(s) 108 a or 108 b. For example, user device(s) 108 a or 108 b may be subscribers to a telecommunication service provider, in which the users are registered or subscribed to receive voice and data services over the network 112. Network 112 may comprise any communication network providing voice and/or data service(s), such as, for example, a 1× circuit voice, a 3G network (e.g., CDMA, CDMA 2000, WCDMA, GSM, UMTS, a 4G network (LTE, WiMAX, HSDPA), or a 5G network.

In general, beamforming has a wide variety of benefits, including, but not limited to, the increased possibility of increased signal strength received at the end user devices, the possibility of providing service to user devices located at the edge of a cell (a.k.a. cell edge) when under normal conditions the antenna could not radiate to that portion of the cell, improved interference handling, and better network efficiency for service providers. In some embodiments, the cell site 106 may be capable of communication with the user device or devices 108 a and 108 b in a particular geographical area by utilizing beamforming. As shown in FIG. 1, a beam 102 may be emitted or radiated from the antenna(s) 104 encompassing a portion of a particular geographical area where the user device or devices 108 a or 108 b are located, providing possible RF coverage for user device(s) 108 a and 108 b to communicate with network 112 via cell site 106.

As stated above, one possible advantage of beamforming is an increased possibility of increased signal strength received at the end user devices. As shown in FIG. 1, user device(s) 108 a and 108 b are located within the beam 102 emitted from the antenna(s) 104 and could possibly benefit from increased signal strength as reported from the user devices in 110 a and 110 b. In some embodiments, Reference Signal Received Quality (“RSRQ”) is used as a measure of signal strength, but signal strength can be a measure Reference Signal Received Power (“RSRP”), Receive Strength Signal Indicator (RSSI), or any other measurement reflective of the received signal strength at a user device. Industry practice currently provides that RSRQ is measured in decibel (“dB”) and RSRP is measured in decibel relative to a milliwatt (“dBm”). For simplicity, RSRQ will be used for the remaining of the disclosure for references to signal strength, but in no way should signal strength measurements be interpreted to be limited to just RSRQ.

In general, the increase of signal strength provided by beamforming can vary from each user device in a particular geographical area due to a large number of factors, e.g. distance between the user device and the antenna, the location of the device relative to the radiation cell edge, objects in the line-of-sight between the user device and the antenna, the topology of the particular geographical area, etc. By way of example, in FIG. 1, as shown user device(s) 108 a and 108 b are located within beam 102 in a particular geographical area and could benefit from an increase of at least 1 dB as measured and reported at 110 a and 110 b. However, due to factors such as user device(s) 110 a being closer to the antenna than user device 110 b the increase in signal strength 110 a for user device(s) 108 a could be higher than user device 108 b. For example, user device(s) 108 a could see increased signal strength of 3 dB and user device 108 b could only see increase signal strength of 1 dB and the average signal strength in the particular geographical area for all user devices 108 a and 108 b would be 2 dB.

By monitoring the average signal strength, as represented in FIG. 1 by the average of 110 a and 110 b of user device(s) 108 a and 108 b in a particular geographical area, an increase or degradation of overall signal strength can be detected. In some embodiments, the one or more user devices 108 a and 108 b are identified within the particular geographic area to select which devices are located within the particular geographical area. This can be accomplished by use of tri-angulation, GPS, round-trip time, trilateration, by identifying the physical cell identifier (“PCI”) serving the user device(s) 108 a and 108 b, or any other means readily available.

In one embodiment, monitoring of the average signal strength 110 a and 110 b could take place in real-time or over the course of 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 60 minutes, 2 hours, 4 hours, or any amount of time determined by a network or service operator or owner. In some embodiments the average signal strength could be monitored by an antenna, radio, element management system, or another element of the network 112. Degradation of overall average signal strength in a particular geographical area, traditionally served by beamforming could be an indication that beamforming has become disabled or deactivated. In one embodiment, a threshold level of degradation of the average signal strength, 110 a and 110 b, of one or more device(s), 108 a and 108 b, possibly indicating the deactivation of beamforming is set by a network or service operator.

FIG. 2 provides a diagram 200 of an exemplary network environment, including an antenna 202, where beamforming is disabled 204, communicatively connected to a radio, which in turn is communicatively connected to an element management system. It should be noted that an element management system (EMS) manages one or more functions or capabilities between one or more network elements throughout a telecommunications network. Referring to FIG. 2, which provides a diagram 200 of an exemplary network environment, including an antenna 202 where beamforming is disabled 204, if a threshold level of degradation of the average signal strength of one or more users is detected then a beamforming status should be determined.

In one embodiment, if a threshold level of degradation of the average signal strength of the one or more devices is detected then a beamforming status of one or more antennas 202 is determined from an element management system 208. This determination can be made by radio 206, or the antenna(s) 202 through the radio 206, by way of a beamforming status detection request 210 to the element management system 208. If the determination that the status of beamforming at the antenna(s) 202 is deactivated then proper steps should be taken to reactivate beamforming 216 from the antenna(s) 202.

In one embodiment the antenna 202 is connected to an antenna line device 212. An antenna line device 212 may include, but is not limited to, a single remote electrical tilt unit, a double remote electrical tilt unit, a dual tower mounted amplifier (“DTMA”), a multi-band tower mounted amplifier, signal splitters, a lightning protection device, a band-pass filter, a duplexer, a Smart Bias Tee, a same-band combiner, a duplex hybrid combiner, a dual-band combiner, a triple-band combiner, or a quad-band combiner.

In some instances a failure of an antenna line device such as 212 could cause beamforming at an antenna to become deactivated 204. In one embodiment the antenna line device 212 is a remote electrical tilt unit and in some instances a remote electrical tilt unit can cause beamforming to deactivate if the remote electrical tilt unit is initially set up incorrectly, fails to maintain communication with an element management system, fails to operate per normal operation, loses power, or for any reason that would cause the remote electrical tilt to cease to operate as it would in normal operation.

In the scenario described above, if the failure of the antenna line device 212, which in this embodiment is a remote electrical tilt unit, is the cause of deactivation 204 of beamforming from the antenna, then the antenna line device 212 is instructed by either the element management system 208 or the radio 206 to reset or be powered back on in the event of power interruption. The element management system 208 then may instruct directly to the antenna(s) 202 or via the radio 206 to reactivate 216 beamforming from the antenna 202.

In yet another embodiment the antenna 202 may be communicatively connected to an antenna calibration unit 214. The antenna calibration unit 214 may reside within the antenna configuration and be communicatively connected to the radio 206 via an antenna calibration port. In some instances, antenna calibration errors could lead to the deactivation of beamforming 204. Antenna calibration errors could include failure of a calibration unit 214 to complete a calibration, the failure of the calibration unit 214 to confirm to the element management system 208 a calibration completion, a failure of the calibration unit 214 to receive a calibration request from the element management system 208, a failure of the calibration unit 214, or other scenarios that would prevent calibration to be completed. In these instances, if the calibration is not completed then beamforming could be disabled or deactivated 204.

In the scenario described above, if the deactivation of beamforming 204 is due to a calibration fault or the antenna calibration unit 214, then the element management system 208 may request another calibration from the antenna calibration unit 214. However, the element management system 208 may skip this request and instead instruct directly to the antenna(s) 202, or via the radio 206, to reactive 216 beamforming from the antenna 202.

Now turning to FIG. 3, a diagram 300 depicting a dynamic beamforming failure detection system 308 is provided for dynamically detecting the failure of beamforming 302 from at least one antenna and taking corrective action to reactivate beamforming 304. The dynamic beamforming failure detection system 308 comprises a processor and one or more computer storage hardware devices storing computer-usable instructions that, when used by the processor, cause the processor to identify one or more user devices 310 a and 310 b present in a particular geographic area, and determine that an average signal strength measurement, shown in FIG. 3 as the average of 312 a and 312 b, of the one or more user devices 310 a and 310 b has degraded by a threshold amount. The processor further communicates a beamforming status detection request. The processor additionally receives an indication that beamforming from the at least one antenna has been deactivated 302 and then determines a failure reason for the deactivation of the beamforming. If the deactivation was caused by a failure of an antenna line device 314, the processor then resets the antenna line device 314 and reactivates beamforming. Additionally, if the deactivation was caused by a beamforming calibration failure 316, the processor reactivates beamforming 304.

FIG. 4 depicts a flow diagram of an exemplary method 400 for dynamically detecting and correcting the deactivation of beamforming, in accordance with implementations of the present disclosure. Initially at block 402 one or more user devices are identified as present in a geographical area. In some embodiments this geographical area is typically served by beamforming. As mentioned previously, the user device or devices may be identified through the use of tri-angulation, GPS, round-trip time, trilateration, by identifying the physical cell identifier (“PCI”) serving the user device or devices, or any other means readily available.

At block 404, the average signal strength of the user device or devices, identified in the particular geographical area in block 402, is monitored. The signal strength may be any measurement of RSRQ, RSRP, RSSI or any other available signal strength measurement available. The signal strength measurements of the user device(s) is averaged and then monitored. The monitoring of the average signal strength measurements can be, in some embodiments, monitored by the antenna, radio, element management system, or another element of the network. Monitoring of the average signal strength measurement of a user device or devices in an area typically served by beamforming can serve numerous purposes. One purpose could be to set a baseline average signal strength for the area when beamforming is enabled or disabled. This monitoring could occur in real-time or over the course of 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 60 minutes, 2 hours, 4 hours, or any amount of time determined by a network or service operator or owner, and if, for instance, a drop in the average signal strength by at least a threshold amount is detected, as in block 406, it could be an indication that beamforming in the area has failed, been disabled, or has been deactivated.

If a drop in the average signal strength of the one or more devices is detected, then a beamforming status detection request should be sent or requested as in block 408. This beamforming status detection request could be initiated or sent by the antenna, a radio, an element management system, or another network element. At block 410, a determination is made indicating that the beamforming status of at least one antenna is disabled. Beamforming can be disabled for a number of reasons and therefore, as in block 412, a failure reason for the deactivation of beamforming should be made. For example, in some instances, beamforming could be deactivated due to the failure of an antenna line device. In yet other instances, beamforming could be deactivated due to a beamforming calibration failure.

At block 414, corrective measures to reactivate beamforming from the antenna or antennas are taken. In some instances, if beamforming is deactivated due to the failure of an antenna line device, then the antenna line device should be reset or restored to power and then beamforming should be reactivated. In other instances, if beamforming is deactivated due to a calibration failure then a new calibration could be requested or beamforming could be reactivated with disregard to the calibration failure.
